Memory
DDR2 SYNCH DRAM NON-ECC MEMORY
Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied
sizes. This chart does not represent all possible memory configurations. The AMD 780V chipset
supports non-ECC DDR2 PC2-6400 (800-MHz) memory.
CAUTION:
You must shut down the computer and disconnect the power cord before adding or
removing memory modules. Regardless of the power-on state, voltage is always supplied to the
memory modules as long as the computer is plugged in to an active AC outlet. Adding or
removing memory modules while voltage is present may cause irreparable damage to the memory
modules or system board.
HP recommends dual-channel symmetric configurations for maximum performance.
For best performance, add the same amount of total memory to each channel and do not mix
speeds. For dual-channel symmetric performance, the total amount of memory in each channel
must be equal. If speeds are mixed, speed will default to the slowest DIMM.
Microtower and Small Form Factor
Maximum Memory
Supports up to 8-GB of DDR2 SYNCH DRAM.
Slot 4 is black and must always be populated. Next
populate slots 3, 2, and 1 in that order. Not all memory configurations possible are represented
below.
NOTE:
For systems configured with more than 3 GB of memory and a 32-bit operating system, all
memory may not be available due to system resource requirements. Addressing memory above 4
GB requires a 64-bit operating system.
